IMPRovED STREET-Box :PoR GAS-mp2s.

The Schedule referred to in these Letters Patent and making part of the same To all whom it may eene-ern Beit known that I, EMERSON MCMILLIN, of Ironton, in the county ot' Lawrence, and State of Ohio, have invented a new-,and improved Streetox for Gas-Pipes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, makinga part of this specilication, and to the let-ters of referv ence marked thereon. v v

The nature of 'my invention consists in providing a street-box for gas-pipes, witha strongly-hinged lid iirmly secured to the box, and capable ot' being raised readily without clearing about it, and without allowing dirt, stones, Sw., to t'all into the box, and having slides in the lower parts of two opposite sides, capable of being raised and lowered insuch a manner that they can be adjusted to the gas-pipe at the same time that the top of the box is adjusted to the level of the roadv 'ay'.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In `the accompanying drawings- Figure l is a vert-ical elevation, yshowing the side of the box having an adjustable slide in it.

Figure 2 is a lateral elevation, showinga side of the box without an adjustable slide, and showing the guard-box of the hinge. f

Figure 3 is a view from the top downward.

Figure 4 is a view from the bottom upward.

Figure k5 is a front view of the Aside slide.

Figure 6 is an end section of the side slide.

Figure 7 is a view of the lid as seen from the under side.

Figure 8 is a side view ofthe lid. y

The same letters mark the same parts throughout.

A is the upper tiange or top of the box. A

Bis the body ofthe box, having, in its opposite sides, openings C C, througlrwhich the gas-pipe can pass, and which are fitted lwith movable slides E E.

The slides E E have semicircular hollows in their lower edges of the size of the pipes to which they are to be adjusted, and are chamfered along the longitu-A dinal edges, so that they may be retained in thel grooves D I) in which they slide.

F is the gnard-box in which the hinge K K works. G is the pivot of the hinge. .l

H is the central opening in the top', through which access is had to the valve-cock or tap in the gas-pipe.

I I are openings in the top, in which the hingepieces K K play.

.I is the lid, and

L is the hinge-pivot, which passes throught-he pivot-- hole G.

In using this box, wheuI to the gas-pipe, or, when laying the pipe, before filling in the trench, I put my box in position, so that the sides B B are vertical, and the gas-pi pe passes through the openings G. C. I then adjust the slides E E by elevatinglor depressing them, or either of them, as the case may require, until the semicireular hollows in their lower edges fit snugly upon the gas-pipe, and the flange A i's on a level with the roadway of the path. I then till in with rubbish, to fix the box in place and make good the roadway, and the box is complete.

When it becomes necessary, as in the case .ofl lire, to shut od' the gas from a house suddenly, the lid of this box can be lifted at once by catching hold on the lside opposite the hinge with the thumb-nail, a knifeblade, or any hard snbstance,and lift-ing, as the hingepieces descend in part, and no dust or dirt can jam the hinge and make it hard to open. v'lo give' a. hold on the lid, a depression is made in the substance ofthe ange A i/n the front of the lid. f

The material, the shape, and the size of the box are not of the essence of my invention, for these may be altered or changethvand the principle of its construction and operation be retained; but the rmanner of-hinging the lid, so that it frees itself of dirt when opening, and is thus readily opened without clearing about it, and so that when raised it offers great resistance to a side-strain on the hinge, and the mode of adjusting the box at once to the gas-pipe, and to the level of the street or roadway, by means of movable slidesiu the sides, are my invention.

. Claim. I claim, as my inventionl A streetebox tbrgas-pipes,of the construction herein described, with a cover and slides formed and operated substantially as specilied.
